+The available HSL solvers are `"ma27"`, `"ma57"`, `"ma86"`, `"ma87"`, and `"ma97"`.
+We recommend using either sequential BLAS and LAPACK backends or a multithreaded version
+limited to one thread when employing the linear solvers `"ma86"`, `"ma87"`, or `"ma97"`.
+These solvers already leverage parallelism via OpenMP, and enabling multiple threads in
+BLAS and LAPACK may result in thread oversubscription.

-The default BLAS and LAPACK backend is [OpenBLAS](https://github.com/OpenMathLib/OpenBLAS).
+Note that the BLAS and LAPACK backends loaded at runtime must be compiled with 32-bit integers.
+The default BLAS and LAPACK backend is [OpenBLAS](https://github.com/OpenMathLib/OpenBLAS),
+and we rely on the Julia artifact `OpenBLAS32_jll.jl` if no backend is loaded before `using Ipopt`.
 
 Using LBT, we can also switch dynamically to other BLAS backends such as Intel
 MKL, BLIS, and Apple Accelerate. Because Ipopt and the linear solvers heavily
 rely on BLAS and LAPACK routines, using an optimized backend for a particular
 platform can improve the performance.
